      What is the EN pin supposed to be?

      On my ESP32C3 I measure VCC (3.3V)

      But on my ESP32S3 I measure 4.6V (with a 3.30V VCC, and 5.01V USB power.)

      The latter I find very strange?

        So, the 4.6V is consistent with the schematic for the Stamp-S3, I see.

        The EN is connected to VIN, not VCC, via a diode, which drops it a little below the 5V from USB.

        This is different from the Stamp-C3, but I guess that's fine.
